Appstle℠ Subscriptions App

Pretty easy integration, Had an issue with a customer having a broken 'Manage Subscription" link, they fixed it. Then had a link that expired, learned Shopify has a 7 day expiration day for links. Now I have to help customers create an account on my site so they can always access their subscriptions. Seem convoluted but appstle tech support was good. 5 Month Update- Customer Service is a highlight of their company, great support!
